## Britannicus or The Secrets of Space

(2107)

The secret motives and decisions of the play are generally confined to the wings where no prying eye or ear, including the spectator's, can perceive them. The stage then becomes an intermediary present between the past and another present happening out of sight but just as significant.

## IMMIGRATION AND DEMOGRAPHICS: CAN HIGH IMMIGRANT FERTILITY EXPLAIN VOTER SUPPORT FOR IMMIGRATION?

(2019)

First generation immigrants to the United States have higher fertility rates than natives. This paper analyzes to what extent this factor provides political support for immigration, using an overlapping generation model with production and capital accumulation. In this setting, immigration represents a dynamic trade-off for native workers as more immigrants decrease current wages but increase the future return on their savings. We find that immigrant fertility has surprisingly strong effects on voter incentives, especially when there is persistence in the political process. If fertility rates are sufficiently high, native workers support immigration. Persistence, either due to inertia induced by frictions in the legal system or through expectational linkages, significantly magnifies the effects. Entry of immigrants with high fertility has redistributive impacts across generations similar to pay-as-you-go social security: initial generations are net winners, whereas later generations are net losers.

## Restricted Maximin surfaces and HRT in generic black hole spacetimes

(2019)

The AdS/CFT understanding of CFT entanglement is based on HRT surfaces in the dual bulk spacetime. While such surfaces need not exist in sufficiently general spacetimes, the maximin construction demonstrates that they can be found in any smooth asymptotically locally AdS spacetime without horizons or with only Kasner-like singularities. In this work, we introduce restricted maximin surfaces anchored to a particular boundary Cauchy slice $C_\partial$. We show that the result agrees with the original unrestricted maximin prescription when the restricted maximin surface lies in a smooth region of spacetime. We then use this construction to extend the existence theorem for HRT surfaces to generic charged or spinning AdS black holes whose mass-inflation singularities are not Kasner-like. We also discuss related issues in time-independent charged wormholes.
